OF PORT HURON, MICHIGAN, A CORPORATION OF MICHIGAN JOINT Applicationfiled Kay 14,

This invention relates to joints, and with regard to certain morespecific features to joints between fittings and pipe or the like.

Among the several objects of the invent on may be noted the provision ofa telescoping joint which is adapted to receive fluid material betweenjuxtaposed surfaces thereof the provision. of a joint of the classdescribed in which there is used an inlet opening; and the provision ofa device of the class described in which said inlet opening is movableto an advanta eous position for permittin insertion of t fie fluidsealing material. Oidler objects will be in art obvious and in partpoint- 1 ed out hereina er.

The invention accordingly comprises the elements and combinations ofelements, features of construction, and arrangements of parts which willbe exemplified in the structure hereinafter described, and the scope ofthe application of which will be indicated in the following claims.

In the accompanying drawing, in which is illustrated one of varlouspossible emobdiments of the invention,

Fig. 1 is a side elevation, showing an assemgily of parts in which theinvention is use Fig. 2 is a longitudinal section taken on substantiallyline 22 of Fig. 1, certain parts being shown in elevation for clarity;

Fig. 3 is a cross section taken on line 33 of Fig. 2; and,

Fig. 4 is a side elevation ring or collar.

Similar reference characters indicate corresponding parts throughout theseveral views of the d -awing.

Referring now more particularly to Figs. 1 and 2, there is illustratedat Fig. 1 a fitting,- comprising in the present instance, by way ofexample, a T. This T is representative of all types of fittings whichmay be used in conof an adjusting nection with the invention.

The fitting 1 is provided with receiving portions 3 which are preferablycounterbored as indicated at numera1s5 for telescopingly receivinglengths of pipe 7. It will be understood that the counterbore 5 isdesirable but that in some instances the counterbore and 1930. SerialNo. 452,452.

the main bore of the receiving portion 3may be the same. However, withthe counterbore, the insertion of the pipe 7 islimited to apredetermined degree. The fit between the pipe and the fitting is suchas to allow a clearance of an order of a few thousandths of an inch sothat a capillary effect is had between the juxtaposed surfaces of thefitting and the pipe when liquid sealing material is introducedtherebetween. The clearance is shown exaggerated in the drawing forclarity.

As set forth in certain co-pending applications on this subject, it'isdesirable that a sprue or opening be provided for delivering fluidsealing material such as solder to the juxtaposed surfaces. If suchopening or sprue is drilled or otherwise formed in fitting 1, thereresults the conditions that sometimes in certain locations in abuilding, the sprue may be located in a downwardly projected position inwhich event it is more diflicult to deliver solder thereto than if thesprue were upwardly located, in which position gravity aids theintroduction of sealing material.

This invention overcomes this difiiculty by making the sprue adjustableso that it may be put into the most advantageous position forintroducing solder or sealing material. It should be understood that thegravitational limitation is not the only one. For instance, it may bedesirable to rotate the opening from a position flat against a ceilingto a lateral or downward position and then feed solder in stick form orsealing material into the opening from below with heat. The generalproposition is that the opening is to be made movable so that it may beput into the most advantageous position regardless of the considerationswhich enter into the choice of such most advantageous position.

In order to accomplish the above, I provide a ring or sleeve 9 which hasan inwardly extending shoulder 11 which slidably fits the pipe 7. Thisshoulder 11 provides an internal groove 13 which slidably co-operateswith a reduced extension 17 of the receiving portion 3 of fitting 1.

The width of the groove 13 is slightly greater than the length of theextension 15; it 100 thereby leaves a peripheral space 17 upon assembly.The ring 9 1s notched as ind cated at numeral 19, said notch 19commumcatin with the internal groove 13.

eferring to Fig. 2 at the left, it will be seen that assembly isaccomplished by first applying the ring 9 over the pipe 7, and thenenterin the pipe 7 into the receiving portion 3 and t en sliding thering 9 into juxtaposition on the end of the extension 15. This leaves aslight-clearance betweenthe pipe 7 and the counterbore 5 of the fittingand also the space 17 between the ring and the end of the extension 17.At the same time there is a sli ht clearance 21 between the ring itselfand 518 pipe. 7.

Upon rotating the ring 9, the notch 19 is rotated and may be placed inany position after assembly of the elements. Inasmuch as the notch 19communicates with the groove 13 by way of the opening 17, saidperipheral opening 17 functions as a distributing channel for sealingmaterial which may be poured into the notch 19. The sealing materialruns around the distributing channel and thence into the clearanceportions 5 and 21. Its distributive action in the clearance portions 5and 21 takes place by capillary phenomenon. It is understood that thejoint is properly cleaned and fluxed prior to operations hereinbeforedescribed.

In Fig. 3 is shown how the notch 19 forms a receiving opening, saidreceiving opening being in communication with the peripheral opening 17for delivery of solder or sealing material about the joint.

It is to be understood that the revoluble notch 19 may be used and theclearance or peripheral space 17 eliminated, in which event the sealingmaterial, introduced into the notch 19, proceeds by capillary phenomenonbetween the ring 9 and the fitting and thence to the surfaces betweenthe ring and pipe and fitting and pipe.

ing drawing shall be interpreted as illustrative and not in a limitingsense.

I claim: r

1. A joint comprising a receiving portion, a member adapted to telescopetherein, a sleeve slidable on said member and engageable with saidreceiving portion, said sleeve having a notch adapted to receive sealingmaterial and deliver same to the assembled joint, said sleeve beingrevoluble with respect to said receivin portion before sealing materialis ap lied and being rigidly held thereto by sal sealing material afterthe sealing materialhas been applied. 4 V

a 2. A joint comprising a fitting having a receiving portion, a reducedextension on said receiving portion, a member adapted to telescope intosaid receiving portion, a sleeve rotatable on said member and slidableinto engagement with said receiving portion, an internal groove in saidring adapted to fit over said reduced extension, said groove beingdeeper than the'extension is long and a notch in the rin "communicatingwith said groove.

3. A joint comprising a fitting having a receiving portion, a reducedextension on said receiving portion, a member adapted to telescope intosaid receiving portion, a sleeve rotatable on said member and slidableinto engagement with said receiving portion, an internal groove in saidring adapted to fit over said reduced extension, said groove beingdeeper than the extension is long and a notch in the ring communicatingwith said groove and sealing material in the space between the fitting,pipe and ring.

In testimony whereof, I have signed my name to this specification this5th day of May,

DAVID E. LINDQUIST.

After the sealing material has been applied,

it hardens. In the case of solder it hardens because the heat which isapplied to the joint during application of the solder is withdrawn. Ifsealing material of an air hardening type is used, it hardens by virtueof its ex osure.

ile pipe has been described herein as the introduced member, it is to beunderstood that rods and the like may also be joined by the fittingsherein described, without departure from the spirit of the invention.

In view of the above, it will be seen that the several objects of theinvention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructionswithout departing from the scope of the invention, it is mtended thatall matter contained in the above description or shown in the accompany-
